Verfahrenstechnische Fortschritte für die Herstellung neuer Materialien – Foliengießen aus Nanopartikeln

It is shown by the example of a ceramic tape casting process, how advances in the field of process engineering lead to improved material properties. One great advance is the possibility of producing nanoparticles in stirred media mills. The nano‐sized particle suspensions can be directly processed to ceramic tapes. The processing of nanoparticles requires specifically adjusted process conditions, but leads to a drastic improvement of the final product properties. Hence, dense and crack‐free ceramic tapes with a higher mechanical strength, a lower surface roughness and a translucent character compared to tapes from micro‐sized powders can be obtained.

Wet‐grinding Technologies with Grinding Media and Visions of Solutions for Centrifuge Mills for the Production of Nanoparticles A complete overview is given on the wet‐grinding technologies with grinding media in stirred‐media mills for comminuting and dispersing of organic and inorganic solid particles in suspensions. With regard to the state‐of‐the‐art and long time experience of the chemical, paint‐ and printing inks industries, it becomes clear that further development of wet‐grinding‐technology is necessary in order to satisfy the requirements of the production of nanoparticles with specific functional properties in the future. Visions of solutions are presented and first results are discussed.
